energy

=Energy page= = = = = = **Kinetic energy** is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy.**Potential energy is converted into kinetic energy**. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy. A waterfall has both potential and kinetic energy. The water at the top of Bridal Veil Falls has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy also happens at Niagara Falls where it is used to provide electricity from the transformation of mechanical and electromagnetic energy to parts of the northeastern United States. List five examples of potential energy. 1.  Car = = 2.  Bike = = 3. iPod = = 4. Television = = 5.  PSP = = List five examples of kinetic energy. = = 1. Running = = 2. Jogging = = 3. Talking = = 4. Screaming = = 5. Jumping = = = = Non-Renewable & Renewable energy = === Non-renewable energy is something that can power another thing but cannot be re-used after use. For example, coal is a non-renewable source of energy, after the coal burns out it cannot be re-used. Although renewable energy can always be re-used. For example when you use wind energy, the wind can always be re-used. But it is not always good for the environment, you still have to cut down trees and use metals to make the turbines. ===

**Geothermal**
= Geothermal energy is steam energy the way it works is very simple, hot water produces steam to cook food or power houses, Geothermal energy comes from hot springs and volcanoes and other natrual steam vents. = = **Solar Energy** = === Solar energy is very dependant on weather conditions, it is a renewable source of energy and will never run out as long as this earth or the sun exists. Solar energy is renewable except is very expensive because the Government will not allow self-installment of the panels meaning the solar panels are expensive. === = **Hydro Energy** =

Hydro energy is energy made by water, this may sound strange but really it does work. Hydro energy is not that expensive compared to solar energy.
= **What is energy?** = = Energy is something that will power other things. For example, Chemical energy comes from food and lets our bodies work, Kinetic energy is when something is moving (motion) and Potential energy is stored energy like our bodies when it is not movie around or just sleeping. Mechanical energy shows alot of kinetic and potential energy because it uses kinetic and potential energy to create mechanical energy. = = = = = = = = = = = = = = =
